Enable TLS 1.1/1.2 in Web browser

In accordance with security requirements for cloud-based applications Map Business Online stopped supporting TLS 1.0 in February 2017. The TLS is part of encrypted Internet communication protocol called HTTPS (you can recognize use of it by seeing https in your favorite browser’s address line). While this measure certainly increases safety of a Web application and sets new level of enterprise data security, unfortunately it comes at a cost – some older Web browsers can’t be used to operate Map Business Online. Good news is that some not-so-old Web browsers can still be configured to support TLS 1.1 and TLS 1.2. Check the table below to see if your browser is up-to-date with security requirements or if it can be configured to provide safe Web surfing experience.
